VIRUS AND BACTERIA

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What do viruses have in common with living cells? They both ____
A
store genetic information
B
have chloroplasts
C
use glucose for cellular respiration
D
have endoplasmic reticulum
Explanation: 

Detailed explanation-1: -Still, viruses have some important features in common with cell-based life. For instance, they have nucleic acid genomes based on the same genetic code that’s used in your cells (and the cells of all living creatures). Also, like cell-based life, viruses have genetic variation and can evolve.

Detailed explanation-2: -Concept 25 Some viruses store genetic information in RNA. So it came as a surprise when in 1971, it was discovered that some viruses shift their genetic information from RNA to DNA. Even so, these viruses ultimately make proteins in the same way as higher organisms.

Detailed explanation-3: -Viruses contain either RNA or DNA as their genetic material. DNA in most organisms is a double-stranded structure, based on Watson and Crick pairing; however, in viruses, DNA and RNA can be either single-stranded or double-stranded.

Detailed explanation-4: -These are particles that contain an outer protein shell called a capsid and an inner core that contains the virus’ genetic information and which these viruses use to continue infection and the spread of their genetic information.

Detailed explanation-5: -Viruses are smaller and simpler in construction than unicellular microorganisms, and they contain only one type of nucleic acid-either DNA or RNA-never both.
